In support of OSHAN <http://sourceforge.net/projects/oshan/>, an open source home area network targeted to embedded devices, I've implemented CC430 support in MSPGCC. It is currently available for download from the OSHAN project page on SourceForge, in a Bazaar repository based on the MSPGCC one at http://sourceforge.net/projects/mspgcc/develop. You can get a copy using:
bzr checkout bzr://oshan.bzr.sourceforge.net/bzrroot/mspgcc-core.cc430 For convenience of those who don't want to deal with Bazaar, I've also made available a tar file with the current contents, and a patch relative to the trunk at the time I started, at: http://sourceforge.net/projects/oshan/files/ A set of examples that work on the TI EM430 developer board are also available from the OSHAN project on SourceForge<http://sourceforge.net/projects/oshan/files/> . I apologize for the lack of convenience, but I'm not building releases of this: it's been tested on Linux (Fedora 9), and you can build it with the buildgcc.sh script that comes as part of the mspgcc-core branch. The binutils patch is for 2.19.1, and the gcc changes are for 3.2.3, but the bulk of the work was in msp430-libc, so supporting the port in other versions of gcc should be pretty easy. My hope is the current MSPGCC maintainers will have a chance to look over the changes and incorporate them into the mainline; I don't want yet another forked MSPGCC. However, I'll maintain the repository that's hosted in the OSHAN project until the changes are integrated somewhere more official. If you have problems, please mail mspgcc-us...@lists.sourceforge.net. Notes on the changes are below. CC430 Support in MSPGCC ======================= This directory contains patches to support the TI CC430 System-on-Chip family. These chips incorporate a MSP430-5xx microcontroller with a CC1101 radio. Only the gcc/gcc-3.2 compiler patches have been updated for CC430 support, but the bulk of the effort is in msp430-libc, so adapting this for a working version of a different compiler should be trivial. See the diffs for the necessary steps. Relative to the baseline MSPGCC system, the patches in this directory incorporate: * Updates to binutils-2.19.1.patch to handle the eight defined CC430 chips * Updates to the gcc/gcc-3.2 configuration files to handle the CC430 chips * Addition of a <cc430.h> include file for mspgcc-libc. * Additional MSP430-5xx module support from JMGross <msp...@grossibaer.de>, including new support for: - CRC16 - Power Management Module * Additional MSP430-5xx/CC430 module support from Peter Bigot <p...@peoplepowerco.com>, including new support for: - Port Mapping Control - Special Functions - Advanced Encryption Standard - RF1A CC1101 Radio Module * Addition of mnemonic defines matching TI headers (e.g., TASSEL__TACLK mapping to TASSEL_0). * Assorted fixes for watchdog support on processors that do not map WDTCTL to 0x0120. Build and install in the normal way.
